8 Ways Windows 8 Speeds Up

Wake Up Faster

In fact, booting Windows 8 is so much faster than booting Windows 7 that resuming from hibernate is no longer significantly faster than booting. With Windows 7, hibernating and resuming takes only about three quarters of the time it takes for a full boot (spending on how many files and programs you have in memory when you hibernate and so how large a file has to be read from disk when you resume). With Windows 8, there’s much less difference; on some of our tests resuming was as fast as booting, but on average resuming is just a little faster than booting.

That’s still a lot faster than resuming from hibernation in Windows 7, at least on a multicore PC like the Core i5 notebook we used for our tests, because Windows 8 shares the work of reading the hibernation file and decompressing the content between all the cores on the system. The full hibernation file is larger than the saved services and drivers that are loaded when you boot Windows, and the extra time it takes to read and decompress the bigger file is often about the same time it takes to load Windows from scratch.

Check which components might be slowing your PC down. The Windows Experience Index rates the performance of key hardware components in your PC like as the CPU, disk drive, and graphics card. This changes in Windows 8 to take account of both improvements in Windows 8 and new and faster hardware; the maximum score is 9.9 (the maximum was 5.9 when WEI was introduced in Windows Vista and increased to 7.9 with Windows 7).
